Selenium geckodriver executes findElement 10 times slower than chromedriver (.Net)
By referring to the previous answer, my issue was solved by below code.
string geckoDriverDirectory = "Path of geckodriver.exe"FirefoxDriverService geckoService = FirefoxDriverService.CreateDefaultService(geckoDriverDirectory);geckoService.Host = "::1";var firefoxOptions = new FirefoxOptions();firefoxOptions.AcceptInsecureCertificates = true;Driver = new FirefoxDriver(geckoService, firefoxOptions);
Yep. You’re definitely hitting the performance issue that is part of .NET Core. It doesn’t happen on Chrome, IE, or Edge, because the driver executables for each of those browsers (unlike geckodriver) listen on both the IPv4 and IPv6 loopback addresses. If you were to specify “::1” as the host for geckodriver with .NET, the problem would disappear.
